The State Government, following the recommendations from the independent Adelaide Beach Management Review, is set to launch nearshore dredging operations at North Haven and Taperoo, alongside expanded mass replenishment efforts at West Beach and Henley Beach South.
Comprehensive Review Prompts New Sand Restoration Strategy
The review, published today, suggests a two-month dredging trial to evaluate the sustainability of using dredging for long-term sand redistribution along the coastline.
Cost-Effective and Community-Supported Dredging Solution
Nearshore dredging was identified as the most economical solution, garnering strong community support during consultations and causing minimal disturbance to residents in coastal neighborhoods.
Government Commitment to Beach Preservation
“Adelaide’s beaches are cherished by many in our community, and it’s crucial to protect and preserve them,” said Attorney-General Kyam Maher. “The State Government is using a scientific approach to maintain sand on Adelaide’s beaches, which are frequented year-round by locals and tourists. Delivering substantial sand to West Beach and Henley Beach South will address erosion, safeguard infrastructure, and enhance amenities to support coastal communities and businesses.”
Implementation of Nearshore Dredging
During the two-month trial, sand will be collected from the nearshore area between Taperoo and North Haven and transported by barge to West Beach, where it will be pumped near the shoreline to replenish the beach. Access to North Haven Marina and West Beach Boat Ramp is expected to remain open during this period, although there will be an exclusion zone around the dredging site.
Significant Sand Replenishment Efforts
In addition to the estimated 90,000 cubic meters of sand from the dredging trial, West Beach and Henley Beach South will receive an extra 200,000 cubic meters of sand over the next year, in line with the review’s recommendation of adding 550,000 cubic meters of sand over the next five years. This additional sand will be sourced from external areas such as quarries or offshore locations, significantly boosting sand levels and beach quality.
Temporary Beach Access Restrictions for Safety
Temporary beach access restrictions may be implemented for safety during sand delivery, as has been done previously. The Department for Environment and Water, tasked with beach sand management, will explore alternative offshore sand sources for ongoing replenishment. Scientific and environmental assessments of the dredging activities will be conducted, along with extensive community engagement.
Environmental Monitoring and Community Engagement
As part of the approval process with the Environment Protection Authority, the environmental impacts of dredging, including water quality and effects on seagrasses, will be closely monitored.
Financial Commitment to Beach Management
A total of $20.6 million has been allocated for beach management initiatives in 2024-25, with dredging operations scheduled for completion by early November 2024, subject to approvals and vessel availability.
